just did a KBB on both mine. The roadster was rated excellent, and was $20K plus, and the coupe was rated good in the $18 plus range. I can live with that in a 6 year old car. The replacement of my passenger door skin looks to have cost me an excellent rating, and about 1500 in the estimated value with KBB...but still happy with their appraisal. Now, getting that price is another story, and taking in account all the performance mods...not even in the ball park...I will drive them till I die...lol
